I don't think there is a single definition of "house sitting" that describes all engagements, but based on what we've seen in the ads, 90% of them involve animals in one form or another... either pets, chickens, horses and yes, even ostriches.
In the house we're at here in Connecticut, we have the pleasure of taking care of Mickey and Henry... two of the sweetest dogs we've ever met who LOVE to go for rides in the car and walks in the woods.

So yeah, this whole house sitting thing is working out pretty slick so far. We love the pets, we love the area and we love the idea of seeing the country in intimate detail by getting to know the towns we live in. It's really quite spectacular.
